I grew up in a world after Contact. I always knew the Peloran were human. Assuming the expanded definition of the word we use now, at least. Of course they’re stronger than most Earthborn humans. And they’ll heal any wound that doesn’t kill them in a matter of hours or days. Though they’ll have to have been real badly hurt to count out the days. They can hear and see things better, and they are naturals when it comes to combat. Put a weapon in their hand, and they’ll use it like they were born to. Which they pretty much were.
